I have dbext installed into gVim - the plugin menu is visible and the help file are accessible; just not helping at the moment!
Suspect it is a connection string problem. I have the following in _vimrc:
" Microsoft SQL Server
let g:dbext_default_profile_WH = 'type=SQLSRV:user=profileName:passwd=profilePassword:dsnname=SQLOLEDB.1:srvname=imsname'
Is this correct?: dsnname=SQLOLEDB.1
Here is my working connection string configuration
let g:dbext_default_profile_mydb = 'type=SQLSRV:user=sa:passwd=password:srvname=localhost\SQLEXPRESS:dbname=mydb'
It seems that only difference between two configuration strings DNS part so it might be DNS problem as you mentioned.

Simply trying to find out the correct syntax for my connection string. Before anyone asks, yes I did look at other SO answers, and no they did not work for me. Here a couple of attempts I made from looking at other SO questions like the one I am asking
Server=(local);Database=SalesOrdersExample;Integrated Security= true
Data Source=(local);Database=SalesOrdersExample;Integrated Security=SSPI
Server=.\\SQLEXPRESS;Database=SalesOrdersExampleDataSet;Integrated Security=true
None of them worked (I have a Console.WriteLine("test"); thrown in there and it works up until I try conn.Open() (opening the connection to database) so I'm assuming that it must be my connection string since nothing gets written after conn.Open())
Console.WriteLine("test"); // works
SqlConnection conn = new SqlConnection("Server=.\\SQLEXPRESS;Database=SalesOrdersExampleDataSet;Integrated Security=true");
Console.WriteLine("test"); // works
conn.Open();
Console.WriteLine("test"); // does not work
So some information about the database is that it's local under my 'Data Connections' in my Server Explorer. I also have the .xsd file in my project so I have linked the Data Set to the current project I am on. Here is a picture representation to confirm that I have both the Data Connection and the Data Set.
EDIT: SO does not allow me to post pictures until I have 10 rep so here is direct link to picture:

Any help is appreciated thank you.
Visual Studio comes with LocalDB database, which is not exactly SQL Server Express database.
Try something like this:
Server=(localdb)\v11.0;Integrated Security=true;
or
Data Source=(LocalDB)\v11.0; AttachDbFileName=|DataDirectory|\DatabaseFileName.mdf; InitialCatalog=DatabaseName;Integrated Security=True;MultipleActiveResultSets=True
If using in c# code, you can use # to avoid problems with backslash characters:
SqlConnection conn =
new SqlConnection(#"Server=(localdb)\v11.0;Integrated Security=true;");
I created my vb.net project to .exe file.
During installation on another machine, one can change the location of installing package to any drive.
In my project, I have set my app.config to point the Database that is available in c:\project.
If I suppose, while installation, when I change the location of installation to **d:** or anywhere, I get invalid access db.
What I want is:
I want to reconfigure my app.config file automatically, by detecting its current db location.
Imports System.Configuration
Imports System.Configuration.ConfigurationManager
Dim config As System.Configuration.Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
config.ConnectionStrings.ConnectionStrings("MyProject.Properties.Settings.MyProjectConString").ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;DataSource=|DataDirectory|\SampleDB;Persist Security Info=True;"
config.Save(ConfigurationSaveMode.Modified)
Where MyProject.Properties.Settings.MyProjectConString is the name of your project and connection string.
Although this is too late to answer as the question is very old but I think this might help someone else in the future.
So, there is a way to change the Connection String value in the runtime. Since connection string is a read-only item like all other items that are on Application Scope under My.Settings so we can't change it using My.Setting.ConnectionString = "Something". But here is the code by which you can solve the issue and change any My.Settings item that is on Application Scope in the runtime.
So the code is,
My.Settings.Item("ConnectionString") = "Something"
simple...
MsgBox(My.Settings.Item("remoteAddress").ToString)
My.Settings.Item("remoteAddress") = "abcserver.servebbs.net"
My.Settings.Save()
MsgBox(My.Settings.Item("remoteAddress").ToString)
You have three options:
1.) Create and use a folder in C:\Databse and set your connection string at design time.
2.)Add the database to the project's data source at design time, then use '|Data Directory|\mydb.mdb' as your connection string.
3.) And if you use sqlserver, you don't need to worry about the location of the database once you have attached the database to sqlserver. You only need to use the proper connection string eg 'Data Source=.; Database = mydb; Integrated Security = False; Username=myusername; Password = mypassword; User Instance = false'.
The above is an example of a sql server with SQL Authentication mode as login, if you use Windows Authentication, set Integrated Security = True and remove both username and password.
This is my first post to this precious website. I am a new learner of vb.net. I am working on a simple purchase project, where i got some errors. But the first thing is which baffled me is:
This is my connection string at module level, on the developed machine.
Public strCn As String = "Data Source = (local); Initial Catalog = PSys; Integrated Security = false; User ID = sa; Password = 123;"
Is it mandatory that Data Source must be the original name of the System Name. I mean If i use (local) or using ( . ), so will it work or not? Because when i copy my project to any other system for further development so every time i need to change the Data source, otherwise i get the error that: "Network-related or instance-specific error occurred......."
Kindly guide me that what i need to do.
When you are developing an application which uses a database server such as MsSQL it is not wise to install the server along with your application in every pc which is installed to. For example what are you going to do if a customer has a local network with 10 computers? Are you going to install SQL server in all 10 of them? And if so what if they need to share data?
So your best approach (based on common practice by other applications) will be to allow the user to install the SQL server where he wants and let him configure your application and point it to the server's location. If you follow that path then the configuration of your application can be in the setup application or in the application itself.
Now about the development phase, I had a similar situation in which I needed to develop the same application in two different computers. What I did was to install the SQL server in both of them with a named instance "sqlexpress" then in the application I used the
Data.SqlClient.SqlConnectionStringBuilder
class to build the connection string. I did something like this:
Public Function getDevConnectionString() As String
Dim csb As New Data.SqlClient.SqlConnectionStringBuilder(My.Settings.dbConnectionString) '<-My original cs in app settings
csb.DataSource = My.Computer.Name & "\sqlexpress"
Return csb.ConnectionString
End Function
Whenever I need a connection string I simply call getDevConnectionString() which returns the connection string based on the computer name plus the sql server instance name. For example:
Dim cs As String
#If DEBUG Then
cs = getDevConnectionString()
#Else
cs = getReleaseConnectionString()
#End If
where getReleaseConnectionString() is the function that returns your connection string configured by the customer.
Hope this point you the right direction...
I'm using an application called Logi info. it requires a connection string to my oracle database. the connection works fine but in order to configure the connection to recive ref cursors from the database, I apparently need to add PLSQLRSet=1 to the end of the string. when I do that I recieve an error "invalid connection string"
Here is my connection string without plsqlrset=1
Data Source=SID; User Id=username; Password=password;
My concern is that PLSQLRSet=1 might be .NET paramater only. Can anyone shed some light on the issue.
Thanks
It appears that the PLSQLRset option is a feature of the OraOLEDB provider (per http://download.oracle.com/docs/cd/B10501_01/win.920/a95498/using.htm).
Therefore I would guess that you have to add Provider=OraOLEDB.Oracle to the connect string -- as shown in the screenshot on the page you linked to -- in order to use this option.
I'm looking to run a batch file on windows xp professional which creates a system odbc data source for a sql server connection. I can do that with:
ODBCCONF.exe CONFIGSYSDSN "SQL Server" "DSN=Kappa| Description=Kappa Data Source | SERVER=10.100.1.10 | Trusted_Connection=Yes | Database=subscribers"
However I need a way to set the sql server authentication to be "With SQL Server authentication using a login ID and password entered by the user." to be set and preset the login id and pass.
Any ideas on how to do this?
thanks in advance
I hope this helps someone, i found that i could not store the username and password. However, I was able to make a ODBC connection without those. The problem was that the connection kept returning an error about how it could not locate the data source name or driver. Only after I removed the spaces from the attribute string could my programs use the odbc connection.
So
ODBCCONF.exe /a { CONFIGSYSDSN "SQL Server" "DSN=dsnname | SERVER=yourservername | Database=Finance"}
should become
ODBCCONF.exe /a { CONFIGSYSDSN "SQL Server" "DSN=dsnname|SERVER=yourservername|Database=Finance"}
create a .reg file with the parameters and merge it in with regedit.exe
Tip: export an existing ODBC profile from the registry to help get the syntax and field names correct
ODBCConf ConfigSysDSN "SQL Server" "DSN=xxxxx|SERVER=yyyyy|Trusted_Connection=No"
seemed to work for me.
You create the DSN the same way for both trusted and non trusted. It is when you use the ODBC connection string that you specify that you want to use trusted connections.
DsnString = "ODBC;DSN=Kappa;Database=MyDBName;Integrated Security=SSPI;Trusted_Connection=True"
